The SPX1117M3ADJ is an adjustable low dropout regulator in the compact SOT223 package. It delivers reliable, clean regulation from a higher input supply to an externally set output voltage, making it suitable for a wide range of board level applications. This listing includes 10 pieces of SPX1117M3ADJ in SOT223 format. Key benefits Adjustable output: Set the output voltage within the regulator's operating range using an external resistor network (resistors not included). Up to 800 mA load current: Supports moderate power regulation for microcontrollers, sensors, and peripheral devices. Low dropout operation: Maintains regulation with a small difference between input and output, improving efficiency in many applications. Small, convenient SOT223 package: Easy to mount on compact PCBs and suitable for spaceconstrained designs. Reliable performance: Part of the SPX1117M3ADJ family, designed for stable operation in typical consumer and industrial electronics. Key attributes Model: SPX1117M3ADJ Type: Adjustable low dropout regulator (LDO) Family: 1117M3 Package: SOT223 Configuration: Adjustable output (external resistor network required to set voltage within the operating range) Maximum load current: 800 mA Quantity in pack: 10 pieces What you need to know Output voltage is set by external resistors within the regulator's operating range. External input and output capacitors are commonly used to ensure stability and transient performance, as recommended by the device datasheet. For proper approval and performance, refer to the official SPX1117M3ADJ datasheet for recommended application circuits and electrical limits. Typical applications Regulating a higher input voltage down to a userdefined voltage within the operating range for microcontrollers or peripheral ICs in embedded systems. Batterypowered devices requiring a compact, adjustable rail with modest current draw within the operating range. Small consumer electronics where a simple, reliable LDO is needed in a spacesaving SOT223 package within the operating range.
